#Decarbonization is a progressive process of reducing our carbon emissions into the atmosphere. These emissions, mainly carbon dioxide (CO2), are a consequence of human activity and the way we produce our energy, as well as intensive livestock farming and agriculture. If we manage to reduce these emissions and reach the so-called net zero emissions, we will be taking a very important step in the fight against global warming.
In the pink house of Valdemarin, a #bioclimatic one, an exemplary decarbonification process has been taking place for many years, which represents an example of efficient energy management. In its design, it has sought to achieve thermal comfort in a natural way, adapting the design and orientation to take advantage of the Sun's energy, both in summer and winter, with passive solar systems. Over time, the use of renewable energy has made it possible to replace traditional fossil energy, achieving a building with almost zero energy consumption and high energy efficiency.

Gráfico con la evolución del Consumo anual de Energía.pdf
Since fossil fuels were eliminated, energy consumption was 77% from 125.000 kWh/year. With the use of #aerothermal and #photovoltaic energy, in addition to improving the use of home automation, best use and efficiency of lights (LED) and modern appliances, consumption has dropped to 65% of the previous level to 23.108 kWh/year.
Production in 2023 has been 17,21 MWh for the first phase and 15,74 MWh for the second, totaling 32,95 MWh.
In absolute terms, appoximately, the house consume 70% of the energy it produces, Pouring the remaining 30% into the grid.
With physics and virtual batteries, consumption is almost zero to day, that is, surpluses are sold to the grid that are used by other consumers.
